Glossary of terms

Advanced Video CODEC (Intra) a type of video coding developed by Panasonic.

CAT5e/6

Category 5e (Cat 5e) and categrory 6 (Cat 6) are twisted pair cables for carrying fast Ethernet signals. Stagebox uses a Gigabit Ethernet interface and so the cables have to be capable of operating at 1000 Gbps.

Genlock (generator locking) is a common technique where the video output of one source, or a specific reference signal from a signal generator, is used to synchronize other television picture sources together. The aim in video applications is to ensure the coincidence of signals in time at a combining or switching point. When video instruments are synchronized in this way, they are said to be generator locked, or genlocked

GND

Electircal Ground connection

GPI / GPO / GPIO

Genral purpose input / output

H.264

H.264/MPEG-4 Part 10 or AVC (Advanced Video Coding) is a video compression format that is currently one of the most commonly used formats for the recording, compression, and distribution of video content.

The precision time protocol (PTP) is defined in the IEEE 1588 standard. Stagebox supports the 2008 revised standard, also known as PTP Version 2, for improved accuracy, precision and robustness

IGMP

The Internet Group Management Protocol (IGMP) is a communications protocol used by hosts and adjacent routers on IP networks to establish multicast group memberships. IGMP can be used for one-to-many networking applications such as online streaming video and gaming, and allows more efficient use of resources when supporting these types of applications. IGMP is used on IPv4 networks

IP

Internet Protocol

IT

Information Technology

LAN

Local Area Network

LANC

LANC (Logic Application Control Bus System or Local Application Control Bus System), also known as Control-L is a protocol by Sony used to synchronize camcorders and cameras

LEDs

Light Emitting Diodes – Used to display Stagebox status

LTC

Linear (or Longitudinal) Timecode (LTC) is an encoding of SMPTE timecode data in an audio signal, as defined in SMPTE 12M specification

NTSC

NTSC, named after the National Television System Committee,is the analog television system used in most of the Americas

PAL

Phase Alternating Line analogue TV standard

PCM

Pulse Code Modulation

PTP

Precision Time Protocol – based on the IEEE1588 standard and the up-coming SMPTE 2059 specification, PTP is the method used by Stagebox to synchronize video over an IP network
